Pro- Submarine Training, 



By late 1943, the shift in emphasis from antisubmarine to 

 pro-submarine warfare was reflected in the selection and train- 

 ing program., Only a limited amount of work was done on the 

 selection of submarine personnel _, the primary concern of the 

 Division G groups being with training. In this, the NDRC 

 training "roups were able to build en their foundation of two 

 years of experience in antis pine training work. Thanks to 

 this background of experience, they were able to develop 

 quickly a well-integrated and effective training program for 

 submarine personnels 



At New London, a submarine training section was established. 

 A UCDVi/R group aided the West Coast Sound School in the training 

 of submarine personnel, and the Woods Hole Oceanographic Insti- 

 tution participated in training in the use of the bathythermo- 

 graph. In 1945 when responsibility for the underwater sound 

 program was transferred to the Navy, provision was made to 

 continue this training assistance under ;. - contracts. 



The problem of the selection of sub i ' ar operators 

 differed considerably from tha of the selection operators 

 for antisubmarine warfare surface craft. On submarines, the 

 sonar watches were customarily filled by assigning men of 

 other ratings 'who were not occupied full tiir 3 There were no 

 rated sonar men until 1945, and then only a few* As a con- 

 sequence, the system followed in the submarine schools was to 

 give sonar operating training to as many men as possible who 

 might be called upon to stand sonar watches. The selection 

 system, therefore, was In a sense a negative one. The problem 

 was not so much to select the men best qualified to be sonar 

 operators, but to weed out those men who might be potentially 

 dangerous due to marked deficiencies of hearing , speech or 

 meter coordination. 



Prom July, 1944 s to January, 1945,, a group from the CoDWR 

 laboratory was assigned to Pearl Harbor to work en selection 

 and training problems. As a result of their efforts , a system 

 was developed whereby men assigned to ComSubpac were classified
